MNLA proudly announces the elevation of Alexis Gagné, Dan Yannaccone, Johanna Phelps, and Martha Desbiens to the role of Principal. This progression marks a significant milestone in MNLA’s ongoing evolution by reflecting the firm’s commitment to cultivating a collaborative, values-driven practice and advancing the next generation of design leadership.
“This elevation represents both continuity and renewal,” said Founding Principal Signe Nielsen. “Each of these talented leaders embodies MNLA’s core principles of transformation, inclusivity, and advocacy. Their elevation reflects years of dedication to our clients, our projects, and our people—and I couldn’t be more confident in their collective ability to guide MNLA into the future.”
Since joining MNLA, each played pivotal roles in shaping the firm’s portfolio and culture:
The four new principals join Nielsen, Molly Bourne, and Rob DeMarco in leading MNLA’s next chapter, building on the firm’s decades-long foundation of design excellence. Together, their collective direction ensures stability across the firm’s project portfolio and empowers teams to deliver transformative, human-centered landscapes.
MNLA’s leadership model emphasizes its ongoing dedication to advocacy and transformation through design principles that have guided the firm for more than three decades and continue to shape its approach to creating meaningful landscapes that serve people, place, and the planet.

Just in time for summer, New York City has opened large new sections of the new East River Park.
Local officials and the design team which includes MNLA, AKRF, One Architecture, BIG, Arcadis, and Jacobs marked the opening of large sections of the new East River Park, which is being rebuilt at an 8- to 10-foot-higher elevation as part of the flood protection provided by East Side Coastal Resiliency. The areas opened to the public on Memorial Day.
This quarter-mile stretch of park brings a variety of new amenities to the community, including basketball and tennis courts, picnic and BBQ areas, a multi-use turf field, open lawn space, and inviting zones for nature exploration and water play. As an addition to the already completed Stuyvesant Cove Park, it now forms part of a broader one-mile span of realized Manhattan coastal resiliency.
